Learn how to handle 404 errors in MuleSoft Anypoint Code Builder (ACB) using the Choice and Raise Error components. In this step-by-step tutorial, we check if a task exists in the database before performing operations like GET, PUT, or DELETE. If the task doesn’t exist, we return a 404 Not Found with a custom payload. If it does exist, the flow continues as expected.
This is Part 5 of the series where we’re building a full To-Do Tasks API with MySQL, Docker, and Anypoint Code Builder in VS Code.
